The base material and the chemically modified MgAl-LDHs went through physical melt compounding in combination with eco-friendly halogen-free flame retardant magnesium hydroxide for the preparation of blending flame-retardant composite materials. The dispersion pattern, structural assessment, thermal stability, and flammability of a composite material before and after the chemical modification with the addition of a varying amount of hydroxybenzoic acid were further investigated. The XRD results indicated that specimen ABS2 presented the characteristic peak of MgAl-LDHs in the range of 2Theta = l0-12°. FT-IR results showed that confirmed the existence of the material’s functional group structure before and after the chemical modification. The TGA results indicated that after calcination under high temperature, a flame-retardant material forms a coke protective layer which can effectively slow down the material’s oxidative decomposition. UL-94 and LOI burning tests were conducted in order to verify the conclusion that adding a small amount of LDHs and reducing the proportion of MH flame retardant can contribute to the enhancement of the thermal stability for a flame-retardant composite material. However, the flame-retardant property of the ABS base material doesn’t enhance with the addition of more composite materials. This result indicated that a small amount of composite material is sufficient for improving the flammability properties of an ABS base material. CHANG, MING-KUN 張銘坤 2017 學位論文 ; thesis 84 zh-TW |
